The invention contemplates broadly, an

improved machine adapted to travel beside aharvester and including a sheaf-receiving means, a platform upon which the shock is formed, means for conveying the sheaves from the receiving means tothe platform,

"means for forming and compressing the sheaves into the shock, and means for bindlng and delivermg the shock.

-In its preferred form the machine embodies mechanism'governed by the sheaf-re ceiving means foractuating the conveying means, and mechanism governed by the V shock forming means and the conveying means for the automatic control of the shockbinding and ClBllVQI'lllg.111GCl1flI11S111,'2tll of which will presently be made clear.

Referring, now, more particularly to Figs.

1. to 4, the main frame consists of long and short side members, 1 and 2, the former of any suitable shape and size and the latter 'preferablyfof channel'iron'with the flanges upwardly disposed. The forward ends of the side members are interconnected by an angle-iron cross-member, 3; and the rear end of the side member 2 is connected with the opposite'member by an intermediate crossmember, 4, which extends beyond the side member, 2, and supports the intermediate portion of a side-member, 5, the forward portion of which is bent at an angle and se cured to the adjacentside-meinber, as at 6. 7 are intermediate longitudinal members secured upon the crossmemhers.

The machine is mounted upon casterable clutch member.

members, 19, of a sheaf-receiving frame or table having cross-bars, 20, inter-connecting the said. side members.

The hub, 21, of the eccentric, 12, is ratchet faced to co-act with a ratchet-faced collar, 22, encircling the main shaft and movable longitudinally thereof upon a key, or feather. 23. 24 is a compression-spring, interposed between the collar, 22, and a boss, 25,.upon the main-shaft.

Mutual engagement of the clutch members, 21, and 22, is normally prevented by'a shifting-arm, 26, pivoted at one 'end upon a bracket, 27, mounted on the main-frame; and having its opposite end formed in a fork, 28, engaging an annular groove, 29, in the mov 30 is a bell-crank fulcrumed upon the shifting arm and having one arm engaged withacam, 21, on the face of the eccentric and'forinedwith a shoulder, 32, which engages the upper edge of the latter arm and serves as a normal stop for the eccentric. The opposite arm, 33, of the'bellcrank is bent downwardly, (Fig. 6) and connected by a link, 34, with a crank-arm, 35, depending fromfa rock-shaft,36, journaled in bearings, 37, mounted on the main-frame; Upon the shaft, 36, are mounted trip-arms,

' 38, eiitending upwardly through the sheafreceiving frame andhaving their upper portions bent substantially horizontallyf 40 is a crank-arm mounted on the said shaft and 7 sheet-metal apron, 47,. curx ed slightly upwardly and then downwardly above the side.

of the sheaf-receiving table of the shocker to serve as a guide for the sheaves and ele vate them slightly prior to delivery.

The shocker is suitably secured to the harvester as by a drawbar, 48, secured at one end to the tongue and at the opposite end to an ear, 49, on the forward end of the shocker. 50 is a spacing link, connecting the intermediate portion oftheframe member, 1,

With the main-frame of the harvester. 7

By virtue of the structure now disclosed it is evident that when a sheaf is dropped upon the trip-arms the latter will be depressed, thereby turning the trip-shaft and causing the crank-arm, 35, and link, 34, to turn the bell-crank out of engagement with the stopcam on the eccentric, whereupon the clutch members, 21 and 22, will co-act with the eccentric to draw the crank, 15, rearwardly.

lVhen the eccentric has made a half revolution, the sheaf-recelvlng frame w1ll have assumed an upright position and thereby set the sheaf upright upon the floor, 51, of the shocker, and in a position to be received by the conveyer, as will presently appear.

7 The sheaf having been removed from thetrip-arms, the spring, 41, will act to restore the bell crank to its normal positlon; and as the eccentric completes its 18V0l11t1011,tl'18 cam, 31, will engage the bell-crank, force the clutch-member, 22, from engagement with its companion and coincidentally the stop, 32, coacts with the bell-crank to stop the eccentric. I

The conveyer mechanism operates in conjunction with and is controlled by the sheafreceiving means. The controlling means therefor consists of a shaft, 52, mounted to the rear of the power wheel, journaled in suitable bearings, 53, mounted under the side members of the main-frame and carrying a forwardly disposed arm, 54, engageable by a pin, or stud, 55, on the side of the eccentric. Upon the opposite end of the said shaft is secured a crank-arm, 56, connected by a rod, 57, with one arm of a bellcrank, 58, fulcrumed on a bracket, 59, mounted on the main-frame. The other arm of said faced hub freely mounted upon the main shaft and engageable by a ratchet-faced collar, 67, encircling the main-shaft, slidable longitudinally thereof on a key or feather, 68, and controlled by a shifting.-

' fork formed on one arm of a bellcrank, 69,

fulcrumed on a bracket, 7 O, mounted on the side of the main-frame. The other arm of the said bell-crank is bent downwardly, and bifurcated, as at 71, to inclose the rod, 57, between bosses, 72, engageable with opposite sides of the latter arm.

It is now evident that during the revolution of the eccentric, the stud, 55, thereon will engage the under side of the lever, 54,

thereby turn the shaft, 52, and force the connecting-rod, 57, forwardly to actuate the bell-cranks, 58 and 69. As the former withdraws the stop-bolt, 60,-the latch-lever will engage and hold the stop-bolt out of the path of the crank.

Coincident with the withdrawal of the stop-bolt, the clutch-shifting bell-crank, 69, acts to force the clutch member, 67, into engagement -.with its companion, and thus actuate the crank.

As the crank is about-to complete its revolution, a stud, 73, on its inner side, engages the upper end of the latch-lever and withdraws the lower end thereof from the stop-bolt, permitting the latter and the shifting clutch member to assume their normal positions, through the medium of an arm, 74, depending from the shaft, 52, and connected by a retracting-spring, 75, with an ear, 76, mounted on the main-frame.

The main crank oscillates a horizontal double bell-crank fulcrumed on a suitable bearing, 77, mounted on the main-frame; and having forwardly and rearwardly inclined arms, 78 and 79, respectively and an outer arm, 80,.connected by a swivel-ended connecting-rod, 81, with the main crank.

On the under side of the arm, 78, (Figs. 1, 2, 11 and 12), is secured an ear, 82, yieldably connected by a spring, 83, with a depending lug, 84, on the main-frame. The said spring serves to retract the main crank to its normal position should the clutch member, 67, be untimely released.

The transverse 'conveyer ispreferably a reciprocating carriage, (Figs. 9 and 10) comprising a suitable frame including uprights, 85, the ends of which are secured between mated horizontal bars, 86, between the ends of which are rotatably mounted flanged wheels, 87, the lower ones of which travel upon the flange of the front cross-- member, 3, of the main-frame; and the up per ones of which are guided by the flange of an oppositely disposed angle-iron, 88, supported by corner-posts, 89, mounted on the main-frame. 90 are sheaf-supporting arms, each having one end secured to the carriage frame, as at 91, and-the opposite end bent rearwardly.

92 is an upright shaft, journaled in suitable bearings, 93, on the frame, and carrying sweep-arms, 94, normally extending toward the left side of the machine. The lower end of said shaft is provided with a crank-arm, 95, normally disposed at an angle toward the left side of the machine and connected by a rod, 96, with-the bell-crank arm, 78.

97 are longitudinal guard-rails, disposed inwardly from the inner vertical plane of the side member, 2, and having their ends bent laterally, as at 98, and secured, respectively, to the corner post, 89 and a post,

99,- secured to the rear portion ofthesaid The said guard-rails form a passage for the sheaves and also serve to prevent entanglement thereof with moving parts of the machine, as will presently appear.

The coiiperation of the eccentric-stud, 55, and lever, 54, is so timed, with respect to the sweep of the eccentric,that themain:

. crank willactuate the conveyers coincidentally with the upending of the sheaves.

.A sheaf having been setupright upon the floor, as previously set forth, the conveyerarms, 94, through the action of the double bell-crank, will be turned rearwardly to the position shown in Figs. 9} and 10, and said movement-will sweep the sheaf toward the arms, 90." Further movement of the double bell-crank then draws the conveyer-can riage, andthe; sheaf is thus conveyed to the opposite corner of themachine and'embrace's the guard-rails,

The longitudlnal conveyer, (Figs; 2, 3 and 15) comprises a suitable frameincluding upper and lower bars, 103, inter-connect ed by a front and intermediate uprights,

104. The upper and lower bars are formed with divided portions, within which are rotatably mounted flanged wheels, 1055, the

' 7 lower of which travel upon the inner flange of the channel-iron frame-member, 2, andv the upper of which are guided by the corresponding'flange of an angle-iron, 2A, se

cured to the posts, 89 and'99. V J At the ends and center of the conveyerframe are upright shafts, 106, journaled in suitable bearings, 107 formed in the frame.

and carrying sweep-arms, 108. The foremost of saidshafts is provided at its. lower end with a bifurcated lever-arm, 109, in which is rotatablymounted a friction-roller, 110, and which is connected by a bar, 111, with lever-arms, .112, mounted on the other of said'shafts. f

A retracting spring, 113, secured to the connectingban'lll, and the carriage-frame tends to draw the bar rearwardly and direct the sweep-arms forwardly, as seen in Fig. 15.

The lower ends of the carriage-frame-upri hts 104 are bent inwardl and conver e forming a V-shaped draw-head, 114, connected-by a rod, 115, with the ball-crank arm, 79. v

The friction-roller 110, travels adjacent a rail, 116, mounted on the main-frame; and serves to hold the sweep-arms, 108,

rigidly in parallelismwith or at right-an lesto the carriage-frame, according as the ClllGCtlOIlOf travel. f

It will now be observed that the conveyors travel toward the front right corner of the be formed integrally with the arm, 109. As.

the conveyer nears theforward, end of its travel, the cam,"117, engages a fixedxupright, 118, on the main-frame, the frictionroller, 110, passes the end of. its track and the cam and upright coact to turn the sweeparins at right-angles to the conveyer as the latter moves to the extreme end'of its travel. The foremost sweep-arms will then be in position to engage. and carry the sheaf rearwardly, and will be held secure against retrograde movement, (prior to engagement of the friction-roller with its track) by' a dog, 119, pivoted on the conveyer-frame and engaged with a shoulder, 120, on the connect-ing-bar.

As the double bell-crank starts to reciprocate, the side conveyer carries the sheaf rearwardly clear ofthe arms, 90, of the other conveyer while the sweep-arms,.94, ofthe latter are assuming their normal position. The front conveyer is then returned tothe opposite corner and the rearward movement of the'sheaf continued untilthe side conveyer nears the position shown in Figs. 1, 2 and 3, forcing the sheaf through the passage formed by the guard-rails and between yieldablei bars, 123, secured to the guard-rails. The. said'bar's extend rearwardly, and inwardly andhave'their free ends bent laterally to embracethe forward sides of the sheaves. As the conveyer nears its rearward position, thefriction roller, 110, passes from its track and the dog,119, is raised out of engagement with its lug by a curvedear, 121, on the dog, engaging a suitable stop. as the upwardly-extended end, 124, of the bell-crank hanger, 59, (Figs. 1 and The spring, 113, then retracts the connectingbar and sweep-arms as previously described. The conveyer then returns to the front, and in a'si'milar manner the foremostsweep-arms convey another sheaf rearwardly, and the intermediate sweeparms carry the first sheaf beyond the intermediate gate members, 123. Upon the third operation of the conveyer, the rearmost sweep-arms carry the first sheafbeyond the rearmost ofsaid gates.v

The shock-forming and delivering mechanism is actuated by a sprocket-wheel, 125, mounted on the main-shaft and connected by a chain, 126, with a sprocket-wheel, 127,

mounted on a counter-shaft, 128, journaled in suitable bearings, 129, mounted below the main frame. The latter shaft carries a spur-gear, 136, engaged with a similargear, 131, fixed on a spindle, 132, journaled in a suitable bearing, 133, mounted on the mainframe. The said spindle carries a small sprocket-wheel, 134, connected by a chain, 135, with a similar wheel, 136, free upon a shaft, 137, journaled in bearings, 138,

mounted on opposite sides of the mainframe. 7

Upon the opposite end of the countershaft is freely mounted abevel-pinion, 139, intermeshed with a bevelgear, 140, mounted on an upright shaft, 14 journaled in a lower bearing, 142, mounted below the mainframe; and an upper bearing, 143, secured to an upper frame having a cross-member, 144, side members, 145, and supported by rear angle-iron posts, 146, mounted upon brackets, 147, extending inwardly from the side members of the main-frame; and square posts, 148, secured in sockets, 149, mounted upon the main-frame member, 4. (Figs. 33 and The shock is formed between side rails, 150, the rear ends of which are bent outwardly and are secured to the rear posts, as at 151; and the forward portions thereof are curved inwardly to join the rails, 97, and 100.

Referring, now, more particularly to Figs. 2, 17 and 18, the bevel-pinion, 139 is formed with a ratchet-faced hub, engageable by a ratchet-faced collar, 153, encircling the counter-shaft and slidable on a key or feather, 154. A compression-spring, 155, interposed between said collar and a boss, 156, on said shaft, tends to force the movable collar into engagement with its companion. The movable collar is controlled by a shifting-fork, 157, freely mounted upon a shaft, 158, journaled in bearing, 159, mounted on a supporting beam, 160, secured to the mainframe. The extended end of the latter shaft is encircled by sleeve, 161-, slidable on a key or feather, 162, and carrying a downwardly curved arm, 163, the end of which normally rests upon the bevelgear, 140. The face of the latter member is formed with a cam, 164, which engages the arm, 163, to slide the sleeve and shifting arm inwardly, thereby forcing the clutch member, 153, out of engagement with its companion.

On the main-frame is fulcrumed a bellcrank, one arm ofwhich, 165, is connected by a retracting-spring, 166, with an car, 167,

mounted on the main-frame; and the other arm of which, 168, is curved below the plane of the bevel-gear, 140, and is connected by crank-pin, 170, on said a link, 169, with a 85 The said bell-crank serves to complete the revclutien of the gear 1n case the clutch should be prematurely disengaged; and to impart the first movement to the gear when forward side of the arm, 163, and serves as a normal stop (Fig. 18).

Upon the inner end of the controlling shaft, 158, is a crank-arm, 172, connected by a link, 173, with a crank-arm, 174, on a shaft, 175, journaled in a bearing, 176, mounted on the beam, 160. Qn the opposite end of the latter shaft is an upwardly disposed arm, 177, engaged by the inwardlycurved end of a push-rod, 178, slidable in bearings, 179, mounted on the main-frame; and connected by links, 180, (Figs. 2 and 3), sliding in bearings, 181, on the main-frame. The rear link, 180, is pivoted to a crankarm, 182, on an upright shaft, 183, journaled in bearings, 184, mounted on the upper frame and a guard-rail. The upper end of said shaft is armed with an inwardlyextending trip-lever, 185.

Referring again to Figs. 17 and 18, a re tracting-spring, 186, is secured to the crank arm, 172, and an ear, 187, on the supporting member, 160. The said spring tends to force the shifting-arm, 163, downwardly against the bevel-gear, and also retract the shaft, 175, the push-rods, 178 and 180, and their associated parts.

A trip-lever, 188, is freely mounted upon the shaft, 175, and provided with an off-set heel, 189, normally embracing the front edge of the adjacent crank-arm. A compressionspring, 190, is interposed between ears, 191, on the rear side of the trip-lever and the ad jacent crank-arm, respectively. 7

The connecting-bar, 111, of the longitudinal conveyer, carries an outwardly-disposed depending arm, 122, (Figs. 2 and 18) which moved rearwardly, (by means to be later disclosed) the arm, 182, the push-rods and lever, 177, will coact to raise the shiftingarm, 163, from engagement with the lower shoulder of the cam, whereupon the bellcrank and spring, 166, turn the bevel-gear until the upper cam shoulder, 171, engages the shiftingarm. This operation turns the trip-arm, 188, directly in the path of the conveyer part, 122. The trip-arm, 188, is yieldable rearwardly and has no effect upon its associated parts when the conveyer travels to the rear. As the latter starts forwardly, however, the depending part engages the trip-arm and thereby raises theshifting-arm clear of the cam, whereupon the-clutch-member, 153, is forced into en gagement and enacts with-its companion to revolve the bevel-gear, 140. The 'conveyer having passed over and released the triplever, the shifting-arm is again brought into engagement with the face of the bevel-gear, and as thelatter 1s completlng 1ts revolut1on,

. the cam coacts with the shifting-arm in disengaging the clutch and stopping the bevelgear.

The bevel-gear, 140, drives a pitman, 192, pivoted on the wrist-pin, 170, and extending transversely of the machine. The free end of the pitman is toothed to drive a pinion, 193, fixed on the lower end of an upright shaft, 19 1, (Figs. 1, 36, 37 and 38) and jour naledin bearings, 195 and 196, mounted on the upper frame and main-frame, respectively. The latter bearing is formed with ahanger, 197, having a bearing-plate,:198,

' vents disengagement of the pitman from which slidably'supports the pi-tman in the sameplane as the pinion. The'hanger' prethe pinion; and is provided with an car, 199,

extending above the pitman to prevent up-' ward displacement thereof. The shaft is supported by a boss, 200, resting upon the bearing, 196.

Upon the intermediate portion of the shaft, 194:, is mounted a spur-gear, 201,

slidable upon a key or feather, 202, and formed'with an elongated hub having a head, or shoulder, 203, resting upon a supporting-collar, 205, freely encircling the hub. and having arms, 206, one of which' is provided with a flanged opening, 207, (Figs.

41 and 12) to slidably inclose the adjacent post, 148. The said arms have depending ends,'208, which support a horizontal segmental guide-housing, 209, within which reciproeates a curved knotter needle, 210, actuated by engagement of the spur-gear, 201 with the teeth of the needle within an opening, 211, in the housing;

The above-described needle-gear supporting member is adjustably supported by a rack, 212, the lower end of which is secured within a socket, 213, formed on said member,

and the upper end slides through a guide bearing, 214, mounted on the upper frame, and is engaged by a pinion, 215, mounted on a shaft, 216, provided with a crank, 217, and 'journaled in bearings, 218,formed in the posts, 148. Downward movement of the rack is prevented by a dog, 219, mounted on a rod, 220, and engaged with the pinion. Said rod being freely inclosed by openings in said posts, maybe turned to disengage the dog when adjusting the-needle and knotter mechanism.

We employ the familiar Appleby. knotte'r supported by a suitable frame, comprlsing (Figs. 3,39 and 40) a collar,'221, adapted to freely'inclo'se the elongated hub of the knotter cam wheel, 222, mounted on the shaft, 141, 'slidable on a key or feather, 223, and having a flange, 224, resting upon the laid a sheet-metalfloor, 249;

trolled by a pinion on the adjusting shaft,

(Fig. 4 1) in the eyeof the needle, and across the mouth of the sheaf passage and its'end is held by the twine-disk,.as customary.

Asthe bevel-gear, 140,1nakes its first half ing'the needle across to coact with the knotter mechanism on the opposite side of the machine. As said bevel-gear makes the last half of its revolution, the toothed pinion and needle-gear reciprocate and retract the needle. r f

The shock is formed upon a platform pivoted at its forward end and preferably comprising a suitable frame including side members, 246, (Figs. 26 to 31) pivoted at their forward ends upon the shaft, 137, and interconnected by cross members, 247, supporting longitudinal beams, 248, upon which is The shaft, 137, carries a fixed roller, 250, connected by an endless, canvas conveyer, 251, with a similar roller, 252, rotatably mounted between the rear ends of the side members. 7

' The said side members are formed with curved runners, 253,, whi -h slide upon the ground when? the platform is released. 'A sheet-metal fender,25et, is secured to and extends between the said runners to prevent the canvas from encountering obstacles.

' The platform is normally supported by longitudinally jdisposed angle-irons, 20%;, mounted above the sides of the platform.

The said angle-irons have their forward ends curved inwardly, offsetdownwardly and secured to the cross-member, 45, of the 7 revolutiomthe rack, 192,1mparts a complete revolutmn of the needle-gear, 201, thus driv:

main-frame, (Figs. The rear ends of said angle-irons are secured to the bracket-s, 147 on the main-frame.

Upon the rear portions of the platform are mounted side-lugs, 255, pivotally secured to upwardly extended bars, 258, curved concentrically with the platform pivot and protruding through openings, 257, in the angle-irons. The said bars are pro vided with transverse notches, 258, which are normally engaged by latch -plates, 259, slidable upon the angle-irons, and provided with longitudinal'slots, 260, through which pass guide-bolts, 261, in the angle iron.

The forward ends of the said la ell-plates are upturned and secured to rods, 262, slidably inclosed by bearings, 263, mounted on the angleirons, and between which and the latch plates are interposed compressionsprings, 264, which tend to force the latchplates rearwardly. Y

The forward ends of the rods, 262, ar

pivoted to lever-arms, 265, carried by a shaft, 266, journaled in bearings, 267, on the main-frame. The said shaft carries an arm, 268, inclined forwardly adjacent the upright shaft, 141, which carries astud, or pin, 269, so positioned that when the shaft is completing its revolution. the said pin will engage the upper side of the arm, 268, force it downward y and thus turn the shaft, 206, to withdraw the latch-plates from the notches, 258, and thereby releasethe platform.

' Upon the shaft, 137, is mounted a ratchet faced clutch member 274, slidable on a key or feather, 275, and engageable with the ratchet-faced hub of the free sprocket-wheel, 136. The movable clutch-member is con trolled by a shifting-fork, 276, pivoted upon the mainframe as at 277, (Fig. 34) and connectedby a link, 278, with one arm of a-bellcrank, 279, fulcrumed on the main-frame. The other arm of the bell-crank is pivotally secured to the end of an arm, 280, depending from the adj acentrod, 262.

By virtue of this mechanism, the endless conveyer is actuated. Simultaneously with the release of the platform, the arm, 280 coacts with the bell-crank to shift the clutchmemher, 274, into operative relation with its companion.

Engagement of the latch-plates with the forward edges of the bars, 256. prevents retraction'of therods, 262, and thereby holds the clutch in operative position until the platform has been restored to normal by means presently to be described.

Referring now, more particularly to Figs. 1 and 2, 282 is a transverse shaft; journaled in suitable bearings, 283, mounted on the in termediate portion of the upper frame. The

end portions of said shaft carry arms, 284.

rmailv forwardlv inclined and connected an: the upper ends of links, 273, by wrist- .s, operating within lengitudinal slots, 286, in said links. The lower ends of said links are pivotally secured to lugs, 270, secured to the sides of the shock-platform.

From the side of the upper frame depend rods, 287, connected by yieldable links, as springs, 288, with links, 272, pivoted to lugs 271 secured to the forward portion of the sides of the platform.

The extreme endsof the shaft, 282, carry crank-arms, 289, normally rearwardly inclined' and yieldably connected byrods, 290, and at springs,.291, with rods, 292 secured to the main-frame. Upon the shaft 282, is secured a substantially U-shaped depending gate, comprising side members, 293, joined at their lower ends with a rearwardly-curved cross member, 294.

The gate, it will be observed, normally decl mes forwardly, but is yieldable rearwardly by virtue of the spring, 291, and the compressor'mechanism, to be later described.

The compressor mechanism, (Figs. 1, 2, 23 and 24) embodies an upright shaft, 295, journaled in suitable bearings, 2 96, mounted on the forward portionsof the rails, 150 5 and a bearing 301, on the upper frame. -The said shaft carries compressor-arms, 297, normally extending diagonally toward the sheaf-passage and adapted to sweep across the mouth thereof. The upper end of said shaft carries an arm, 298, normally extended toward the left side of the machine and actuated by a crank, 299, mounted on the needlegear shaft, and having africtionroller, 300, mounted on its wrist-pin.

compressor-shaft, 295, carries an in- \Vztl'LllY-CllSPGSGEl arm, 302, connected by a swivel, 303. with a rod, 304, telescoping a. hollow shaft, 305, connected by a swivel, 306, with an arm, 307, mounted on the shaft, 282, and normally rearwardly inclined. The hollow shaft incloses a compression-spring, 308, interposed between the rod, 304 and the farther end of the inclosing shaft, which spring holds the arm, 298, yieldably against a stop, 309, mounted on the frame; and also aids the retracting link, 291, in forcing the gate forwardly. I

As the needle-gear shaft, 194, is turned in thedirection indicated by the arrow in Fig. 23, the friction-roller, 300, will engage and carry the arm, 298, to'the position shown in broken lines, and thus swing the packer,- arms rearwardly at the time the kn'otterneedle is driven toward the knotter-hook. The forwardmovement of the arm 298, also forces the compression-rod, 304, rearwardly, and thereby imparts further pressure on the gate to compress the rear side of the shock, as will later appear.

As the needle-gear shaft reciprocates, the compressor mechanism is retracted by the spring, 308.
